Application filed September 18, 1912. Serial No. 721,107. l

To all 'whom t may concern.'

Be it known that we, (l) CHARLES H. Louw, (2) JOHN R. Grumman' citizens of thc United States, residing at (lleveland, in

the county of Cuyahoga and State of Ohio,

have invented a certain new and useful Improvement in Bottle-VVashers, of which the followingI is a full,` clear, and exact description, reference vhad to the accompany- 1C indrawings.

his invention. relates toa paratus for cleaning bottles and similar articles, and has for its general objects to provide'an appa'- ratus of this character which will be largely 16 automatic inl its operation and which will soak, clean, and sterilizebottles in a very eiilcient manner. The apparatus described herein is similar in its general features tv that disclosed in the application of John R. Gruetter, filedl April 17, 1912,' Ser. No. c 691,478, but diferen-,from the' apparatus of the aforesaid application in several features, such -as theconstruction of the bottle carrier, the construction of the bottle soaking means- '25 (including the means for supplying liquid to the insides and outsides of the bottles). Further objects of the invention are to`pr0- vide means whereby the temperature of the cleansing and soaking liquid may be maintained substantially uniform throughout the operation of the apparatus, as well as to improve thegeneral construction and operation of apparatus of this type. Generally stated, the invention may be defined asl con- 3S sisting of the wmbinations of elements set forth in the claims hereto annexed and illustrated in the drawings forming art hereof, wherein: Figure 1 represents a pIlan view of an apparatus constructed in accordance with the invention; Figs. 2 and 3 Sideelevations of the front and rear portions of the a pa` ratus respectively; Figs. 4 and 5 side e evations of the parts of the apparatus shown respectively in Fi 2 and 3, the views be 4o ing taken from t e opposite side; Figs. 6 and 7 are longitudinal sectional views of .the front and rear portions ofthe apparatus, respectively; Figs, 8 and 9-transverse sectional views corresponding a proximately to the lines 8 8 and 9-'-9 of ligs. 2 and 3 respectively.

The apparatus disclosed herein' comprises generally; a tank or receptacle havingpplut0 rality of .liquid containing 'coniirtments therein; a pair of rails in said tnkr receptacle extending longitudinally thereof 4and above the compartments; a rins or washing box in each compartment, eachv4 X415 being provided with a plurality of no'fzzfles;

connections vfor removing cleansingfl I lizing liquid from each compartme -operating nozzle box; .anrendlessboigtlgarrier mounted on the rails; means fo'mppsh tively feeding or advancing` saidlaifrier along the rails with the mouths of thelottles supported thereby presented towalylp' j nozzles so that the cleansing from the nozzles may be appli tles as 'thy latter are' conveyed Y rails by /astep-byslep movement conveyer n the tank or receptacle arrange` Ae i @ma aewsiiing ma aeg/tened to im collect and remove any labels that may be -when necessary to `replenish the same; a

brush at the discharge end of the tank adapted to operate upon the bottoms of the bot! tles as theyv pass thereunder; a final internal brushing and rinsing mechanism at the discharge end of the tank and to which the b ottles are fed (preferably by the same mechanism which feeds them through the tank) w ith means for automatically brushing-and rinsingtheinteriois of the bottles as they pass through the final apparatus.

vTli'e tank or receptacle referred to hereinbefore' is `Similar to that shown in the ap- -plicationof Gruetter referred to hereinbefore. This tank comprises side walls l, a

bottom '.Wall 2, a ro'nt wall 3, a rear wall 4,

and a plurality of transverse partitions 5 which divide the tank or receptacle into -a plurality vot' liquid containing' compartments A, B, C, aridi) Each partition is providedV with a slot G therein, above the level of the liquid which may be contained within the compartment. and similar slots 7 and 8 are provided in the front and Vrear walls of the tank or receptacle (sce Figs.' 6 and 7), said slots being in substantially the same horizontal plane Iand being provided for the passage of the endless label conveyer which will be described hereinafter. Each of the compartments A, B, and C is provided with an overfiow pipe 9 projecting upwardly from the bottom of the tank. The `tops of these pipes are in substantialliv the. same horizontal plane, whereby the lcvcl of liquid*i in ull of the compartments will be substan- Atially the same. rlhe compartments A. l,

and I) are provided each with a connection 1() whereby liquid may he supplied thereto from a pipe 11 (scc Fig. H). The compartments A, B, and C contain heated liquid and, for thc purpose of heating the liquid therein, a steam pipe 1Q is provided having a branch 13 extending to cach ot' thc compartmcnts A, and C. 'lhccompartments having been illed to the proper level, thc supply of Awater oi' other liquid thereto through thel pipe 11 will be cut'oiflry means of the valve 11.8. ln compartments A, li. and thc water supplyv pipil is extended below thc connection 10 and communicates with an' annular chamber 1lb, the lower portion of the chamber communicating with the compartment below the connection 10, as by means of the branch pipe in' (see Figs. 8, 21 and 22), and a steam branch pipe 13 projects into an upwardly directed tapering passage or nozzle l14 within the casting containing the annular chamber llb and discharges at its upper end into the annular chamber Il, preferably in line with the pipe section 11 thereabove. iVith the valve 11a closed and the valve 13 open, it will be Vapparent that steamltlowing through the nozzle-14 will \create a circulation of the water from lthe bottom of the compartment (A, B, or C) throughthe annular chamber 11b and through the connection 10 into the upper4 part ofl the compartment. In this manner, the steam will effectively and uniformly raise the temperature of theliquid in each of the-compartments.

The compartment D is intended to contain cold water forthe'tinal rinsing of the bottles passedl through the tank; hence no' steam supply is provided for this compartment, the water being .admitted directly to" the compartment through 'the connection .10. The steam'supply branch v'13 is provided with a suitable handeoperated valve 13Il by which the supply of steam to'each compartment may be controlled. In addition, we prefer to control the supply of steam to each com- I partment by thermal conditions therewithin, and a construction by which this result mayI be realized is .illustrated in Figs. 4, 5, 8, 19 and 20. In addition to the valve 13", each ln'anchpipe 13 is provided with a valve, in-

dicated genprally at 13b, the stem whereof is connected with a diaphragm in the diaphragm chamber 15. The diaphragm in this chamber (not shown) is flexed by means of compressed air supplied i t0 the chamber through a pipe` 16, -and l the fiow of air through the pipe 16 to the diaphragm chamber is controlled b v temperature conditions within the compartment corresponding to such chamber. A construction for controlling thc flow of the valve'opm-ating fluid (in this casu compressed air) is shown more particularly in Figs. 19 and 20. -In these views, 16 dcnotesthe pipe bringing air or other inid under pressure from a source of supply. 4l`his`lprcssure fiuid is conducted tln'oughpa valve. which -is shown in Fig. 2() as comprising va vertical inlet' passage 17 formed in thecasting constituting the hack otl a gage 18. the vertical passage 17 communicating with achamhcr 1) which-is also in communication 'with' a second vertical passage 2() communicating with the pipe 1G. The gage referred to is conveniently supported by thc side wall 1 of the receptacle. The flow of pressure fluid from the passage. 17 into the passage 20 is conlrolledby a valve ball 21 which is mounted within the operating mechanism and the'thermostatic element is secured to'tlic outer end of the screw and the opposite end of the screw bears against a member 25 which is connected to a rod 25 having its inner end cou- -nected to the corresponding end of a tube 25" projecting into the compartment from the side wall. The rod 25 is confined witliin a flexible metal tube'i. From this construction, it will be evident that the lever 22 and the valve 21 will be operated by the -ex- A pansion and contraction of the tube 25b to cause the opening and closing of the valve 21 according as the temperature falls below or exceeds the limits for which the thermostat is set.. The pipes 16, 16 may be pro-v vided with a .suitable strainer 16" (See y Fig. 19).

' flange, 29.

`Each compartment A, D, C, and D is con'. v nected with the suction side of a pump, one

of the pumps being indicated at 26, the de livery side of the pump discharging into onel of the washing boxes referred' tohereinbefore. ln order to prevent foreign anat? ter entering and interfering with the operation of the pump, a strainer is employed on the intake side of each pump.- In the construction shown herein, each pump is provided with an inlet pipe 27 connected to the side wall 1 of the tank and having an extension 2S projecting into the corresponding compartment oi"- the tank and prol vided with an upwardly inclined end. This upwardly inclined end is provided with a The opposite side wall of the tank is provided, above the pipe end 28, with a U-shaped plate 30, the upper end oi the plate constitutingr a yoke for the reception of the upper end of the strainer, said strainer being preferably a pipe 3l having its upper end closed by a cover 313 and its lower end fitting over the upwardly directed end of the comiection The pipe 3l is provided with a large number of fine pcriorations and is detachably secured in place by means oi the 'yoke 32 pivotally supported by the frame 30 andcarrying a clamp screw 32" adapted to engage the upper end oi the strainer and thereby force its lower end downwardly upon the pipe connection 2S. llolts 33`connecting the flange 12) and plate 30 constitute with these members a cradle or supporting frame for thil strainer. Then desired, the stra'mers may be conveniently removed through the upwardly inclined extensions 34 of the tank wall and the doors 35.

.erating handle 45".

The label conveyer, washing'boxes, bottle carriers, sediment trays, although associated with the tank, will be described hereinafter, it beingr sufficient to state that these parts are within the taiilraiid' beneath the cover 36, which cover is preferably composed of anuniber of ren'iovable plates ordoors.

Nozzle or washing boxes.

Each compartment is provided with a nozzle box or washing box, all of the boxes being practically identical in construction.- One of these boxes is shown in transverse section in Fig. 8 and comprises generally a casing 37 having at one end thereof a connection 38 for the reception of the pipe 39 which conducts liquid from the delivery side of the pump 26. It will be vobserved that thebottom otA each box is upwardly inclined from tlte connection 38 to the opposite end of the box and that the bottom is inclined upwardly on opposite sides of the central portion thereof as sliownat 37 (see Figs. 6 and 8)' to facilitate the drain- -1ng and cleansing of said b'ox toward the said connection. Each washing box is provided With a cover having a suitable number of nozzles 40. Each of these nozzles is provided with a plate, preferably circular in outlineand having a central aperture 41 and four apertures 42 Anear the outer periphery of i the top plate and 1o cated about ninety, degrees apart. The central aperture is intended to discharge Water into the 'interior of al bottle thereabove while the lateral apertures 42 are intended to discharge water upwardly along the neck and outer. side of the bottle to assistiti removing` the labels and dirt therefrom.' lach washing box is conveniently` applied to thetank by being inserted' through an opening in4v the side wall opposite that through ,which the pipe connection 39 extends, the box being provided with a flange 43 adapted to engagethe side wall of the tank and being provided with one or more doors 44, carried'by-a frame 45 which is pvoted at one end to lugs projecting from vthe fiange 43 and has its outer end' detach- A ably connected to another pair of lugs 4projecting from said fiange, as by means of a hinge pintle 4:6. Each door. is adjustably mounted on its frame and may be forced to a scat in the cover flange 43 by means of a screw 45 extending through a yoke carried by the frame and bearing'against the. door, the screw being provided with ant op- By opening these doors, the nozzle boxes may be conveniently cleaned Whenever necessary or desirable. Cast With each box are lateral braces 37b having flanges adapted to abut against and be secured tothe side of the tank, as Iby bolts.

Bcneath each washing box there is located a tray, the outer edges of which are in engagement withthe'side -walls of the tank. Each trayv (indicated at 47) slopes downwardly from the outer Aedges thereof to a central opening 48, which is located directly above the label conveyer, (which will be described hereinafter). Below the tray and the label conveyer, and between the same and the top of the liquid in each compartment there is interposed a screen. This screen is generally rectangular in outline and comprises av peripheral supporting frame 49 for a wire gauze Abottom 49, the bottom sloping downwardly from the side of the tank opposite the door 35 and the screen being slidably supported on suitable rails 50, extending transversely of the compartments and having ends projecting beyond the side wall and beneath the door 35. Y

-Each liquid containing. compartment ofthe tank is provided with a lateral drain pipe a, b, c and d respectively, each drain pipe communicating with the bottom of its compartment andhaving a` valve f therein. These lateral pipes, communicateat their outer ends with the discharge pipe Q, with which the overflow pipes 9 are also in communication.

Label conveyer.

The lebel conveyer is of substantially the saine construction as that disclosed in the application of John R. Gruetter hereinbefore referred to. This label conveyer, as is the caso with that of thc aforesaid application. comprises generally a plurality of perforalcd metallic plates 51 extending trans,- verselv of the tank or receptacle each plate having its opposite ends shaped to form a segun-.nt of a cylinder. as shown at 52 and 53 (sce Figs. 25 and 2G). The ends will be given a curvature substantially concentric with the pivotal connect-ion between the adjacent plates. but the 'surface 53will he of sulliciently less diameter than the surface 52 to receive thoreover the semi-cylindrical end of the next adjacent plate. Each plate is connected at its lateral edge with what is in effect the side plate of a chain link, said side plate being shown at 54 and having an inwardly directed flange indicated at 55 in Fig. 25 and in dotted lines by the same -numcral on Fig. 26. rlhe vertical flange on cach side plate 54 is preferably deflected outwardly at one side to receive betweenitself and the edge of the plate 51 the adjacent end of the next side plate. Coperating with cach side plate 54 is a side plate 56 and the ends of the side plates are connccted by rivets 57 extending through the circular portions thereof, there being spacing sleeves 58 interposed between said plates. The plates 54-56 of the sleeves v58 form in effect chain links which are oonnected to and movable with the plates 51 of the conveyer, the wholeconstruction roviding a perforated metallic conveyer w ich can be driven in substantially the same manner as a leather or other endless belt. Instead of forming the screen by simply perforating the plates 51, as in the case of the earlier application, we make the perforations in the plat 51 of comparatively large size and cover Ithe upper surface of each plate with a wire gauze 59 which serves to retain sediment, labels, etc., that may be discharged on top of the conveyer. The conveyer is supported at its side edges by the inwardly directed flanges 60 of a pair of angle iron rails, the rails being supported on the lower edges of the slats 6, 7 and^8 in the partitions.

The conveyer is driven by means of a pair of sprockets 61 mounted on a common drive shaft 62. The sprockets are adjustably mounted in slide ways 63'and their shaft G2 is driven by a chain 64, sprocket 65 on the shaft 62, and the sprocket 66 on 'the shaft 67. As is the case with the conveyer shown in the earlier application, the front part of the conveyer passes over uide wheels 68 located near the bottom o the tank and rearwardly of the sprocket`61, whereby the part of the conveyer passing hetween 61 and 68 is inclined downwardly and rearwardly to facilitate the dropping of labels. etc., therefrom. The-conveyer passes beneath the bottom of the tank and around the guide wheels 69 and 70 at the rear end of the tank. As is the case with the construction shown in the earlier application of Gruetter, a. pipe 70a, extending from the rear compartment. is arranged. in proximity to the rear and inner surfaces of the conveyer and is adapted to discharge liquid through plates to dislodge labels or other sediment that may adhere to the conveying surfaces thereof. 'A shield. 71 is provided between the pipe 70a and the'parts at the front of the apparatus, and a removable screen 72 is slidably supported at the bottom of this plate in laterally extending guide-waysl 73, whereonlabels, etc., dislodged from the conveyer may be collected and removed as 0ccasion may require.

Bottle conveyer. Coperating with the washing boxes and with the final brushingand rinsin mechthe perforations in the conveyer ont toi.

upper and a lower casting. connected by 100, these openings being disposed ninlety4 cisely the same manner with reference toI the openings of the jet nozzles as in the construction hereinbeore described.

The ends of", the frame comprising the straps 97 and the cross bars 98 are connected to the side links '81 by means of anges 106 projecting from the angle bars 98 and bolted to plates or flanges 95 projecting Jfrom the links. The links 87 are identical with those described in connection with ne preceding form of conveyor.

Above eachwashing or nozzle box and coperating with the nozzles in cleansing the outsidcs of the bottles are transversely arranged hoods 107, each hood being preferably a sheet-metal plate formed to present a series of transversely extending corrugations 1.08 having their downwardly directed apiccs109 preferably above the center of a jet nozzle. striking thereagainst to be directed downwardly, on the bottoms'o the bottles and assists in removing the dirt and labels therev from.

Final brushing and rif/icing apparaitra cleaning apparatus at the rear or discharge end of the machine. This nal brushing and rinsing apparatus Lwill ibe described briefly i since practically all of the features thereof are set forth in the application o'Grruetter referred to hereinbeiore.

The; mechanism comprises generally a vertically reciprocable bo); 110 having a flexible water supply connection 111 and provided with a plurality of hollow spindles 112 each having a brush 112a at its upper end which, when the boxy is in its lo'vverrncst position, will be retained Within a guide tube or sleeve 113 having a Jfrustoconical end 111i adapted to cooperate with the upwardly projecting frusto-conical bottle month supports on the conveyor, the brushes being moved through the guides 113, frustoconical extensions llfl and into thelbottles When the latter are brought into alinement with the spindles. The brush spindles are provided with intermeshing gears 115 driven by a master gear 116 slidably keyed'ufpon the vertical shaft 117, The final rinsing tubes 1118` are mounted on the rear end of the box 110 and are adapted to discharge water into the bottles just prior to their delivery from the apparatus 119 denotes a trough through which the spindles 112 and tube 118 project, said trough collecting the Water discharged from the bottles and in turn discharging this water into the waste pipe 120.

rThese hoods cause the liquid f 121 denotes a clamping frame mounted above` the brushing and rinsing spindles and provided with a plurality of ottoni clamps 122. This frame 121 is adapted to 'reciprocate to 'a slight'extent and is provided with a cross head 123 which is sleeved upon guiderods 124.-. The trame 121 is Suspended byl links 121a (see Fig. 24) depending from the Yinner ends of the horizontal levers 125. The

outer ends ci these levers are provided with a plurality of apertures 125a 'by 'means of which they v'may be connected tothe out- Wardly projecting arms 126 of angle levers 'i the upwardly extending arms of which (126) are connected by means of a spring 127 and rods 128a The levers 15-1262L are rotatably supported on a shaft '129. This construction forms a yielding support for the frame 121. From the lever arms'l26 depend the rods 130, one on each vside of the frame Work 131. rlhese rods are conveniently guided by projections 132, 133, on each side of the frame 113a and the box 110, respectively, and each is provided with adjustable collars-134y and 135. By this construction, as the box 110 moves downwardly and is near the lower end of its stroke, the projections 133 enga-ge the collars 135, pull downwardly upon the rods 130 to thereby rotate the levers 125--126a and thus move the bottle clamp frame 121 away from the bottles and permit ythe advance ofv the bottle conveyor therebeneath; and a slightly further movement in the same direction causes the collars 131 to engage the projections 132 on the ranicll and move the same downwardly against the action of the springs 136, which yieldingly support said frame. rl`his con-joint operation of the frames 113a and 121 enables the bottle Conveyor with the bottles thereon to be ad" vanced the next step toward the rear or discharge end of the apparatus. The shaft 117 which carriesthe master gear 116 for driving the brush spindle gears 115 is provided at its lower end with a beveled l gear 117a Within a housingV 137 which'contains bevel gea-r 138 meshing with the gear 117a and mounted on a shaft 139.

The box 110 is reciprocated by a rock sha-ft 140 having a pair of arms 141 thereon, said arms being each connected at oneend to the box by means of a. lin'k 142 (sec Figs. 3 and 5) and each having a countenbalancin `Weight 143 at its opposite end.A The sha t vkl 0 is rocked by an arm 144; connected to wie,

opposite end connected to e iinl; 153. which .are intended to be engaged ibfdpawls,

is itself connected to the rock arni 1&1-, shown at 154:. 1t Wiii- 'he eijqdent that the movement oi' the shaft 11,6 to raise and lower the 'box 116 Willi. .also open and close the vaive 151 to suppiy Water to the hex when needed and to cnt ed such snppiy when the hoz is inwcri-ri'.

Botie omweg/er feeding mechanism.

Thehottie conveyer, as previously statedfw comprises a pair of side chains, each hav ing ratchet teeth 88. These ratchet teeti an these pewls are mounted on r slidabiy mounted Within the upper portion of the tank. The rods may he hoiiow or tubular, for purposes of lightness, end ere each provided With'a piuralty of pawi car- ,riers 156, which may he convenientiy bolted thereto. The pan/ls 157 are pivotaily mounted between the downwardiy projecting iower ends otiie carriers 156 and are adapted to abut against the ratchet teeth or shoulders 88 on the conveyor chain. For the purpose of supporting and guiding the rods 155 in their movements9 the upper portion or cover for the tank is provided on each side with a plurality of brackets, eech bracket coneprising a frame 158 which may ne bolted or otherwise secured to the side of the tank cover.. These frames project inwardly and support each a pair of vertically spaced roliers 159, 160, in rolling engagement with which the pani carrying rods 155 may be reciprocated. it will be observed that this arrangement contemplates no Verticai re ciprocation ot the rods 155. Such reciprocation however is rendered unnecessary by the drive for vthe rods, which drive is secured by means o e transverse rock shaft 161eXtending across the tank and having a pair of vertically extending .rock arms 162 connected thereto, the upper end of each rock arm being connected to a paw] carrier rod 155 by means of a link 163 pivotally connected to-said rod. This link, as shown, is preferainy composed ot adjustabiy connect ed sections, whereby its e'ective length may be varied.

m'wng mechanism.

Parts ot' the driving mechanism have necessarily been referred to hereinhefore in connection with the various parts of the apparatus. 161` denotes a motor Which drives two of the puinpsQG which supply the front compartments and B. and 165 denotes a motor driving a shaft 166 -for the rains from the shaft 166.

'me ne pumps supplying Water to the co1npartments C and D. This shaft is extended to a point between the rear ci' the tank proper and the front of the iin-al brushing and rins4 ing apparatus which has just heen described. At its rear end the shaft is provided with :a sprocket on which is mounted n. noiseiese chain 16'?, the chain passing over a sprocket 168 on the shaft 1519 located at the contra portion et' the apparatus.' This shaft is provided at the end opposite the gear 138 with a pniiey 1,69 over which passes a belt 1"?'07 said belt passing over a puiiey 17() {Figz connected to and thereby driving n sheit 171 on the opposite side ot the appa- This shaft is provided with a worin 17:2 'Within a' casing (see Figs. 3 and 9) which Worin meshes with Worm gear 123 on the 'transverse Simft 148.

Projecting from the shaft 148 is a crank arm 175, the outer end of which is ceni nected 'with a slide 176 mounted within an arni 177 which is pivoted at one end (as shown et 1?'8) at. point remote from the shaft 14:8. rihe central portion of the arin 177 is eonnected ny means oi' a link 179 with an erin 186 rigid with the rock shaft 161 which operates the pawicarrying rods 155. An adjustahie connection is provided between the iinir 179 and arm 1.80 by aI pinfand-slot Connection. .The purpose of rocking the shaft 161 by the mechanisn'i described is to impart a slow recovery stroke and a quick feedin increment to the pawl carriers, the parts [eing practicalii7 at rest ico during the greater part of the vertical movev ment of the end of tue crank arm 175. This construction provides a simple and eil'icient means for :feeding the bottle conveyor along the rails by an intermittent inovei'nent While enabling the bottles to remain in n stationary' position a sufficient length of time to insure the filling or the bottles with liquid. and the eiiicient rinsing 0i' the outside of the bottles by such liquid.

The shaft 7 1 ext-ends to the, iront ot the apparatus, where it is provided with u Worin 181 wit-hin a casing 182 (see Fig. 11). The worin meshes with worin gear 188 on the shaft 67, said shaft carrying a sprocket Wheel 66 by which and the chain 6i and the sprocket 65, the hib/el couveyer is driven.-

The shaft 188 4is mounted in curved slots'A 188, the shaft being'e'ariied .by arms 1855 pivoted on the shaft 185, whereby the brush 102 may be adjusted for diterent lengths of bottles. 4 i

The bottle eonveyer. passes over guiding and supporting,r Wheels 193` and'194 located respectively at each side of the ront and hack ot the apparatus, the first-mentioned wheels being preferably carried by a 105 supported in journal boxes 196 adjustably mounted in guide Ways 197 projecting forwardly from' theff ,paratus. By means ot' the adjusting screws 198, the tension of the conveyor may be adjusted,r from time to time. 1t will he noted that the rails 74e and 02 are extended at the front and rear of the machine in such manner as to guide the conveyor conveniently to the Wheels 193, 194:.

Each compartment A, B, C, and D is provided with a door 199 having one or more transparent panes :200 to permit inspection of the interior of the tank. Each door is rovided with upwardly extending lugs Q01 y means of which it may be pivotally connected to lugs projecting rom lthe side ot' the cover. Each pane rests uponY a ledge 202 provided in the door frame proper, said ledge having a recess for the reception of a gasket 203 against which the pane can hear. The pane is clamped in place by means of a frame E20-l having one or more openings for the pane, the clamping frame being secured to the body ot the door by means oi screws Q05, there being,r a gasket 200 interposed hetween thc clamping frame and the perforated portion of the pane thereheneath. The doors are conveniently retained closed by means of: buttons 207. ln addition to the doors 35 and 199, the tank is provided with' a plurality of man-holes having removable covers 205i.

The driving connection between the shaft 171 and the conveyor mechanism operated thereby is obtained by means of a clutch Q00 l(see Fig. 3) and this clutch is thrown by a yoke 209a connected to a rod 210 extendingr the full length of the apparatus and having an operating handle 211 at each end thereof, whereby 'the mechanism may be put into and out of operation from either end of the apparatus.

With the apparatus constructed as described, it is believed that the operation will be clear. The motors 161- and 165 having been started in operation and the shafts driven thereby having been set into rotation, water will be taken from the compartments A, B, C, and l) and forced by the pumps Q6 into the Washing boxes 37 and through the nozzles 40 and into and around the hottles'therealoove. T he conveyor 'will be ted .through the tank structure, above the compartments and washing boxes by an intermlttent movement, imparted by 'the reciproassegno cation of the pawl carriers 155. The bottles on the conveyor, atte having been rinsed by the cold liquid from the eomp'artn'ient D wheels 194e, the operator removes the clean bottles therefrom.

'lhe labels loosened by the action of the ,liquid on the outside of the bottles are deposited upon the label conveyor 51 and carried by said conveyer to the front 0f the apparatus Where, through the downward and rearward inclination. of the conveyor between the sprocket Wheels 61 and 68 and the action of the cleaning pipe they are dislodged and dropped upon the screen 72, which can be conveniently Withdrawn from its support from time to time to enable the labels to be disposed of as occasion may reuire.

rlhe liquid falling; from above upon 'the eonveyer is filtered by the conveyor screens, and by the screened trays 49, therebeneath, so that the liquid, when it returns to its particular compartment, is quite effectively cleansed from foreign material. -Should,

however, any suchi matter remain in the liquid, the strainers 31 will serve to prevent the same from entering the pumps and clogging the same. Nhen it is desired to remove andpclean these strainer-s, this operation can he conveniently effected by opening.

the doors 35, unclamping the leales 32 from the strainer covers, and withdrawing the strainer tubesbodily through the upwardly l Y and outwardly extending projections oi' the tank side.

Any liquid that may be needed to replenish the compartments from time to time may be admitted through the pipe 11 and warming fluid may be circulated through the compartments and the temperature of is a space or compartment E which con-v t =ins no liquid, but which serves as a dra-ining station between these compartments as well as; a space tor the accommodation ot the shaft 161.. This-compartment also Will receive more or less liquid from the bottles and from. the bottle and label conveyors and
